After i bought TG2 i wanted to make a bigger render of this:
http://forums.planetside.co.uk/index.php?topic=7815.0This project was-is full of problems. Not all of them are related to TG2.
But i learned many things on the way
Anyway!
There were black parts. I tried many things. No cure!
I am too stubborn sometimes. I didn't wanted to say there is a bug etc. before i tried all i know.
After some days i left it and tried it after a couple weeks later with Oshyan's fill light setup.
It looked good at first.
I couldn't see bad black parts in the render at first. But then i saw something else on the space ship.
Checkerboard kind of patterns.Light and dark parts .
I tried ones more all i know with the render settings etc. No cure!
If the image hadn't in the first place black bad renders everywhere i would have seen it maybe earlier.
These dark and light parts where mostly on the prominent reflective parts.
After many tests i think there is a problem in this "Reflective shader" .
There are some posts here on the forum but i could not find this specific kind of problem.
If this is a known problem i am wasting my and your time now ...
To see if the problem isn't related to my object i tried it with basic objects .
There was the same checkerboard pattern.
Then i thought maybe it is the same on other native TG2 objects.
Please try this:
1- Open a new default scene in TG2.
2- Shaders+Add Layer+Other surface Layer+Reflective shader
3- Delete all other nodes above "Reflective shader" . (with or without them it is the same)
4- Go to Full Render and make the image 200x200 for faster testing.
5- Render... There is no problem!
6- Open the Reflective shader node and pull the "Reflection softness" slider to the right ( 0.8 ) .
7- Render again...Yes here it is! Checkerboard pattern.When i first saw that it has to do with the "Reflection softness" i thought after some test that there is a threshold but i think now it gets only less prominent with smaller settings.
After lowering the number of samples to 1 in the Quality tab of the Reflective shader the pattern vanishes .
Interestingly if you use only 1 thread in the "Full Render" Advanced tab you do not get this problem too.
So if you try this with a computer that only have one core you might not get this pattern at all.I tried many other settings but the only working solution for me were these 2 above.
I looked at the older images that i made with the free TG2 v2.2 and i could not see such patterns.
It looks like it is new to this build to me.
I use Windows 7 Ultimate 64 bit and TG2 with animation v2.3 (build 2.3.20.1) 64 bit .
